SIGNAL-LAMP.

Specification of Letters Patent.

Patented Aug. 26, 1919.

. Application filed June 27, 1918. Serial No. 242,150.

b all whom it may concern 1 Be it known thatI, FURMAN D. SPEAK, acitizen of the United States ol. America, residing at New York city,county and Statoof New York, have invented a new and useful Signal-Lamp,of which the following is a specification.

My invention relates to signal lamps for railroad use, particularly ofthe type termed classification lamps. structurally, it is essentially animprovement upon the lamp shown and described in my former Patent#816,509 of March 27th, 1906. The object of the present invention is toprovide in a classification lamp novel features of construction wherebyit may be readily adjusted and put in condition for giving the desiredsignal. Classification lamps are located on the front end of locomotivesand motor trains, and are arranged to throw a light directly ahead and-a corresponding light laterally at the outer side of the train, one ofsaid lamps being provided on each side of the locomotive or motor. lVhenthe light whichis projected ahead and laterally by each lamp is white,it indicates that the train is an extra. lVhen there is no light itindicates that the train is a regular. When the light is green, itindicates that the train is in sections.

Ordinarily, different lamps are required for these different signalingpurposes. By my improved construction, a single lamp may be used toindicate these three different conditions.

In the drawings:

Figure 1 is a vertical section of my improved classification lampmounted upon a suitable bracket.

Fig. 2 is a horizontal section thereof through the center of the lens.

Fig. 3 is a perspective view of one form of the lamp support or bracket.

1 represents a bracket which may be of any suitable constructiondesigned to support the lamp and hold it in the desired position. 2represents the base of the lamp, which, in this particular case, is ofcircular outline and is designed to slip into the opening in the ring ofthe bracket 1 and to be held in any suitable way against rotation as bya pin 3 carried by a spring 4, the pin being projected, through the ringof the bracket and into a hole in the base of the lamp adjacent theretowhen the lamp is in place. As shown in the drawings, in Fig. 1 the lampbase 2 may have two oppositely positioned holes for the reception of thepin 3 so that the lamp may be held in either one of two positions 180apart. 5 represents a burner of any suitable type as the source oflight. 6 represents the main body of the lamp. In this particular case,7-7 represent plain white glasses or lenses which are arranged 90 apartin openings in the main body 6. 88 are green glasses or lenses which arelocated diametrically opposite to the two white lenses. Assuming thatthe lamp shown in F ig. 2 is placed on the front end of a locomotive ormotor at the right hand side, the front lens and the right-hand oroutside lens will show white. Obviously, to prevent confusion, the otherlenses should be hooded or shielded in some manner suitable to preventlight from passing therethrough. To that end, I provide a shieldcomprising opaque plates or shutters 9-9 which are arranged in avertical plane to stand between one set of lenses and the source oflight. The ends of these shutters 9 9 are provided with pivot shafts10-10 which pass out through the lamp body 6 and are provided with oneor'more operating handles 11-11 which may be conveniently locatedoutside of the lamp, whereby, by turning the handle or handles, theshields may be swung over to hood the green lenses or the white lensesat will. In the particular form shown in the drawings (Fig. 2) theshields 99 are positioned to cut off the light from the green lenses,hence, with the lamp mounted as aforesaid, the signal lamp wouldindicate, if lighted, that the train was an extra. If it should bedesired to indicate that the train was infsections the spring held pin 3would be withdrawn and the lamp body turned 180 so as to present thegreen lenses at the front and outside of the train and the shutters orshields 9-9 would then be turned over or reversed so as to cut oil' thelight to the white lenses, then located at the rear and inner side. Ifthe train is a regular, the burner could be removed or the lightextinguished. Thus, by this comparatively simple arrangement I am ableto provide in a single structure means for indicating any one of thethree signals characteristic of classification lamps. ()bviously, thestructure of the lamp must be such that it can be turned angularly inthe bracket so as to position the desired lenses forthe proper signalingeffect, and it is also essential that the shields shall serve to cut offthe light from tWo lenses at the rear and inner side of the lamp,OthGlWlSG confusion WOLIlCl result. The shield 9 9 may be mademodifications in the details of construction may be resorted to Withoutdeparting from the spirit and scope of this invention, and that I haveattempted herein to describe and illustrate onlyone preferred form ofsaid invention.

That I claim is: I

1; In a lamp, a body having two sets of oppositely arranged lightopenings With glasses of corresponding color in one set and glasscsofanothercolor in the other set, both glasses of one set being arrangedadjacent to each other, means for. supporting the lamp for angularadjustment to present the desired set of glassesin the desired position,a source of light Within the body, with means mounted within the lampbody and movable therein for cutting off therays of light from thesourceof light to one or the other set of glasses at will. i v

2. In a lamp, a, body having two sets of oppositely arranged lightopenings With glz'tsses of corresponding color in one set and glasses ofanother color in the other set, both glasses of one set being arrangedadjacent to each other, means for supporting the lamp for angularadjustment to present the desired set of glasses in the desiredposition, a source of light Within the body, With movable means Withinthe lamp-body for cutting off the rays of light from the source of lightto one or the other set of glasses at Will, said means comprising ashutter pivotal'ly mounted in said lamp body.

3. In a lamp, a .body having two sets'of oppositely arranged lightopenings With glasses of corresponding color in oneset and glasses ofanother color in the other set, both glasses of'o-ne. set being arrangedadjacent oppositely arranged light openings With glasses ofcorresponding color'in one set and glasses of another color in the otherset, both glasses of one set being arranged adjacent to each other,means for supporting the lamp for angular adjustment to present thedesired set of glasses in the desiredposition, a source of light Withinthe body, With movable means Within the lamp body for cutting oil therays of light from the source of light to one or the other set ofglasses at will, said means comprising a shutter pivotally'm'ounted insaid lamp body in a substantially horizontal plane, and means externalof the lamp body for operating said shutter. i Y V 5."In a lamp, a bodyhaving tWo sets-of oppositely arranged light openings With glasses ofcorresponding color in one set and glasses of another color in the otherset,-both glasses of one set being arranged adjacent to each other,means for supporting the lamp for angular adjustmentto present thedesired-set of glasses'inthe desired position, a source of light Withinthe body, With movable means Within the-lamp body for cutting off therays of light from the source of light to one or the other set ofglasses at will, said means comprising a-shutter pivotally mounted insaid lamp body in a substantially horizontal plane, and means externalof the lamp body for opera-ting said shutter comprising a handleconnected to one end of the pivotal portion of said shutter 7 F URMAN D.SPEAK.
